1. Conceptual Runoff Models for Material Transport Estimations
Sammanfattning : Catchment-scale material transport models are today important tools for water and environmental management. However, modelling of material transport is extremely complex due to the physical, chemical and biological processes involved. LÄS MER
2. Sediment transport from source to sink in the Lake Baikal basin : Impacts of hydroclimatic change and mining
Sammanfattning : Different magnitude, intensity and timing of precipitation can impact runoff, hillslope erosion and transport of sediment along river channels. Human activities, such as dam construction and surface mining can also considerably influence transport of sediment and sediment-bound contaminants. LÄS MER
3. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling
Sammanfattning : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. LÄS MER
4. Impact of hydropower regulation on river water geochemistry and hyporheic exchange
Sammanfattning : Hydropower regulation of rivers exhibits a threat to the riverine ecosystems. Fragmentation of flow, landscape disturbances, and water retention are key features of regulated catchments, resulting in reduced floods and geochemical tr¬ansport, non-natural water level fluctuations, and thus disturbed exchange between the river and the aquifer.
